Answer:

The confidence level is equivalent to 1 – the alpha level. So, if your significance level is 0.05, the corresponding confidence level is 95%. If the P value is less than your significance (alpha) level, the hypothesis test is statistically significant.

Hi there!

If Jeremy walked 6/8 of the way to school and ran the rest we know that Jeremy ran 2/8 of the way. We can simplify this further to get to our simplest form.

6/8 ---> 3/4 Simplified.

So your answer is Jeremy walked 3/4 of the way.

Whats the center and radius of (x+3)^2+(y-5)^2=64
Alexandra [31]

Answer:

The answer to your question is Center = (-3, 5)  radius = 8

Step-by-step explanation:

Data

                (x + 3)²  +  (y - 5)² = 64

Process

Because of the characteristics of the equation, we conclude that it is a circle.

Standard form of a circle:

              (x - h)² + (y - k)² = r²

In this form of the equation, the center has coordinates (h, k), just change the signs.

And to get the radius, just get the square root of r²

h = -3

k = 5

r = 8

Center = (-3, 5)

radius = 8
